I need help Moving two tables back together

[Warpug]

I have two tables with thousands of records, all of which on the one tab were given a "dupstat" if they were a duplicate. In this instance duplicate doesnt mean a duplicate in the sense of data duplicate, but a business processing duplicate. So my problem is, that when the items from tab a, were filtered and moved to tab b and the columns were limited, the rest of the data from tab a wasnt moved with it. All the work was done on tab b and I need to figure out a way to get the data back on to tab a somehow. I dont know how to do this if multiple rows can have multiple columns with similar data. Here are the data on the two tabs
TAB A:

acct#	loan#	amt	total	diff	daydif
